Difference Between Acute and Chronic Respiratory Acidosis

Key Difference

The key difference between acute and chronic respiratory acidosis lies in the onset and duration. Acute respiratory acidosis occurs rapidly due to a sudden failure in ventilation. Chronic respiratory acidosis develops over a longer period, often due to ongoing lung diseases like COPD.

Comparative Analysis

1. Onset:
   • Acute: Rapid.
   • Chronic: Gradual, over time.
2. Causes:
   • Acute: Sudden lung failure, obstruction.
   • Chronic: Long-term respiratory issues.
